Answer:
The correct answer is: Zero, Option c.
Step-by-step explanation:
The price elasticity of demand shows the change in the quantity demanded of a commodity due to a change in the price of the commodity.
The cross-price elasticity is the change in the quantity demanded of a product because of a change in the price of related good.
The cross-price elasticity is calculated by finding the ratio of proportionate change in quantity demanded and proportionate change in price.
Cross-price elasticity in this situation will be

=
![(0)/(30)](https://img.qammunity.org/2021/formulas/business/high-school/3th9rplp1hlmn81etig45rv8e8ajuvxelg.png)
= 0
The cross-price elasticity is zero. This implies that the two goods have no relation.
